Before I begin, Happy Fourth of July! I recently upgraded from an '09 MBP 13" to an '11 MPB 15". I spent hours waiting for the Migration Assistant to do its magic by wifi (no firewire cable). After letting it run overnight and seeing very little progress, I decided it was time to try something else. I cloned the hard drive from my 13" MBP and simply swapped out that drive with the stock drive in my 15" MBP. It took a little less than an hour using SuperDuper!. Everything works as if I had been using this computer all along. In fact, it seems to have worked a little too well. Having dealt with PCs over the years from time to time at home and in the office, I know this is virtually impossible with Windows. In my case, however, it seemed to work like a charm. My question/concern is: Am I missing something? It is recognizing all of the components properly but it just seems too easy. All of the apps, files, and settings work perfectly as far as I can tell. Take care everyone and enjoy the holiday!
